Having seen it in Midnight in The Garden movie, I've wanted to go there for so long! There is no charge for entry, closes at 5pm I think.
In our first week in Savannah we took a cab there ($15 from Historic District) then went back again in the second week when we had a car as i wanted to also see Danny Handsford's grave in the Greenwich Cemetery next to Bonaventure.
Beautiful trees with Spanish Moss, lots of history. Sad little graves of children who died of influenza, a beautiful Jewish section (not because of segregation as someone thought, just because it's always separate areas in cemeteries) Lots of history.
Walked around for a long time...kept the car with us the second time, reading scallywag reports in reviews (!) but seemed pretty safe at this time of year and lots of maintenance people there tending to trees and shrubs. In Feb it was still beautiful, but I'm sure more so in the Spring and Summer.
If you do want to see D.H grave (the young man shot in the true story) turn left when you reach Bon. gates, without going in, go down the bordering road past the Memorial Garden and then into the Greenwich Cemetery, inside turn left, Lot 6 Block G row 8.
There is a Bonaventure bathroom at front gates!
